The test is performed as a solid phase immunoassay (ELISA) in B2GP1 coated microwells. Controls, Calibrators and patient serum samples are incubated in the antigen coated microwells to allow antibodies present in the serum to bind. Unbound antibody and other serum proteins are removed by washing the microwells are detected by adding an enzyme labeled anti-human lgA, lgG, lgM or lgA/IgG/IgM conjugate to the microwells. These enzyme conjugated antibodies bind specifically to the human immunoglobulin of the apropriate class. Unbound enzyme-labeled conjugate is removed by washing. Specific enzyme substrate (TMB) is then added to the presence of antibodies is detected by a color change produced by the conversion of the TMB substrate. The reaction is stopped and the intensity of color change, which is proportional to the concentration of antibody, is read by a spectrophotometer at 450 nm. Results are expressed in ELISA units per milliliter (EU/ml).

The QUANTA Flash® ß2GP1-Domain1 assay is designed to run on the BIO-FLASH® instrument. This platform is a fully automated closed system with continuous load and random access capabilities that automatically processes the samples, runs the assay and reports the results. It includes liquid handling hardware, luminometer and computer with software-user interface. The QUANTA Flash® ß2GP1-Domain1 assay utilizes a reagent cartridge format, which is compatible with the BIO-FLASH instrument. The assays included in this submission, the QUANTA Flash ®2GP1-Domain1 marketed by Inova Diagnostics Inc. (9900 Old Grove Road, San Diego, CA 92131) and HemoslL "AcuStar Anti-ß2GPI Domain 1 marketed by Instrumentation Laboratory (180 Hartwell Road Bedford, MA 01730), are equivalent assays. Therefore all data stated hereafter and referred to as: QUANTA Flash ß2GP1-Domain1 data is equivalently also valid for HemosIL * AcuStar Anti-ß2GPI Domain 1. Recombinant ß2GP1-Domain1 protein is coated onto paramagnetic beads, which are stored lyophilized in the reagent cartridge. The reagent pack is prepared for use in the BIO-FLASH system by pressing down on the grey lid of the reagent pack to pierce the induction seals on the reagent tubes. Once the seals are broken, the beads are rehydrated by adding the entire contents of the vial of resuspension buffer to the bead reagent tube using the transfer pipette supplied with the kit. Only the hole above the bead reagent tube is accessible at this point. The beads are then mixed with the resuspension buffer by pipetting up and down 30 times. This amount of mixing ensures complete resuspension of the beads. The label covering the remaining three reagent holes is now removed, and the reagent cartridge is then loaded onto the BIO-FLASH instrument. Samples are also loaded onto the instrument in sample racks. A patient serum sample is prediluted 1:10 by the BIO-FLASH with system rinse in a small disposable plastic cuvette. Small amounts of the diluted patient serum, the beads, and assay buffer are all combined into a second cuvette, and mixed. This cuvette is then incubated at 37°C. The beads are magnetized and washed several times. lsoluminol conjugated anti-human IgG antibodies are then added to the cuvette, and again incubated at 37°C. The beads are magnetized and washed repeatedly. The isoluminol conjugate is oxidized when Trigger 1 (Fe(III) coproporphyrin in sodium hydroxide solution) and Trigger 2 (urea-hydrogen peroxide in sodium chloride solution) are added to the cuvette, and the flash of light produced from this reaction is measured as Relative Light Units (RLU) by the BIO-FLASH optical system. The RLU are proportional to the amount of isoluminol conjugate that is bound to the human IgG, which is in turn proportional to the amount of anti- ß2GP1-Domain1 antibodies bound to the corresponding ß2GP1-Domain1 on the beads. The QUANTA Flash® ß2GP1-Domain1 assay utilizes a predefined lot specific Master Curve that is uploaded onto the instrument through the reagent cartridge barcode.

An enzyme-linked immunoassay (ELISA) for the detection of IgG antibodies to complexes formed by oxidized low-density lipoprotein (oxLDL) with ß2-glycoprotein I (ß2GPI) in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (antiphospholipid syndrome).

The IgG Anti-AtherOx Test Kit is an indirect ELISA detecting IgG anti-oxLDL/B2GPI antibodies. Diluted serum samples, calibrator(s), and controls are incubated in microwells coated with the oxLDL-ß2GPI complex. Incubation allows the IgG anti-oxLDL-B2GPI antibody present in the samples to react with the immobilized antigen complex. After the removal of unbound serum proteins by washing, anti-human IgG antibodies, labeled with horseradish peroxidase (HRP), are added forming complexes with the bound IgG anti-oxLDL-B2GPI antibody. Following another washing step, the bound enzyme-antibody conjugate is assayed by the addition of a solution containing tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) as the chromogenic substrate. Color develops in the wells at an intensity proportional to the serum concentration of IgG anti-oxLDL-B2GPI antibody. Results are obtained by reading the OD (optical density or absorbance) of each well in a spectrophotometer. Calibrator sera are provided, with the IgG anti-oxLDL-B2GPI antibody concentration expressed in G Units. A log-log regression analysis is performed with calibrator values plotted against calibrator mean ODs. Controls and patient results are determined from the calibration curve.
